React App failed to compile after install

Question

After running the install script, the server starts and serves a page displaying the same text after the 'Failed to compile line.'

I'm running Windows 10 and auto update just updated my pc today, right before I did the create-react-express install.

Answer 1

Seems to be an issue with autoprefixer latest version. I referred https://github.com/postcss/autoprefixer/issues/1328 and tried downgrading autoprefixer in my project and it works now. Try:

npm install [email protected]

Happy coding!

Answer 2

I also faced this problem. And it looks like a problem with autoprefixer version, so i changed the version.

npm install [email protected]

I tried this, and it works perfectly.
